Ok, just an update on progress. I've fixed the duplicate IPN issues, but still need to fix the cancellation IPNs from renewing the subscription. Once fixed will send you a new release for testing tomorrow.

The explain the issue further what is happening is a recurring profile created IPN is being sent, which we don't need as our API call was successful; so this IPN is now ignored. Next is a payment IPN is sent shortly after recurring profile created IPN, which again we don't need as our API call has already confirmed success; so this IPN is now ignored 1 time if the basket is still logged as being subscription signup and updates the basket to subscription payment. This means the next payment IPN will renew the subscription properly.

Similar situation is happening with cancellations, but the IPNs are renewing instead of cancelling despite their status being set correctly so is taking a little bit longer to investigate.

I apologize for any inconvenience this has caused you.

When can i expect the fix to test?

It'll be completely fixed today as I'm retesting the entire usage in multiple scenarios.

I've sent you the latest build. I've tested and fixed all usage scenarios. Subscriptions appear to be working perfectly fine now. Cancellations are also now working fine. Single payments continue to have no issues.

Please note I observed the below issue, but have yet to find a fix or workaround. The below appears to be a bug in CBSubs it self and not the gateway thus far. However, it's an extremely specific scenario so you are highly unlikely to encounter it in normal usage situations, but you will if you're doing resubscribe testing.

If you Subscribe, then Unsubscribe shortly afterwards, then Resubscribe shortly after Unsubscribing, there will be no Expiration Date. For some reason it fails to calculate, but this is a calculation done deep in CBSubs and have yet to discover why it does this. Everything else appears working fine (subscriptions, renewals, cancellations, and even refunds).
